Charged with exploring three fourths of the planet, Ocean Sciences a large and inclusive field. The oceans are important for our quality of life, its fisheries and mineral resources, for transport, and its role in the climate system. Some of the exciting research emerging is related to the role of the oceans in the climate system. Researchers are studying the ocean’s involvement in the exchange of heat, water vapor, and momentum; sequestering heat at depth; and exchange and cycling of greenhouse gases and other biogeochemically important compounds. Because of its broad focus—and because the ocean is such a vital part of the Earth system—this page encourages dialogue with scientists, engineers, policy-makers, educators, and others interested in science.
The focus of this page is marine-related science, including the study processes in environments ranging from the coast through the open ocean, and they develop and use a wide range of highly technical instrumentation ranging from remote sensors to autonomous devices to ship-related sampling gear. It will include highlighted research and information from the AGU journal JGR-Oceans and information that would interest AGU’s section Ocean Sciences, among others.

Mission: AGU promotes discovery in Earth and space science for the benefit of humanity.

The salmon is an icon of Quinault culture, heavily featured on totem poles and in artwork on tribal buildings, and a traditional meal at family gatherings and in tribal rituals. Now it’s also a symbol of climate damage.

Incorporating random variation of temperature, humidity, and wind offers a computationally cheap alternative to improving resolution in an Earth system model when predicting when Arctic sea ice will disappear.

Scientists on the R/V Endeavor had a problem: While they were out at sea, the coronavirus spiraled around the globe into a pandemic. And they’d barely missed the window to fly through Europe back home to the United States.

"I started my own countdown (to Earth Day) at the 50-day mark. As an oceanographer, each of my tweets highlight an ocean topic, scientist, technology, educational resource, etc. I’ve connected all of mine as one Twitter thread, so by clicking on the first one, you can scroll through all of them on the same page."

Alas, the massive gatherings and celebrations for the 50th anniversary of Earth Day are pretty much cancelled across the globe. But the countdown started for many of us when it was 50 days to go, and now, with 25 days until Earth Day 2020, I’m sharing where I am seeing some fun posts on Twitter. J...

How do you use science to make a real impact on ecosystems and communities? Lauren Alexander Augustine explains how the NASEM Gulf Research Program is investing the massive Deepwater Horizon criminal settlements toward an ambitious mission.

Water masses formed off southeastern Greenland may contribute more than previously thought to the variability of the Atlantic Meridional Overturning Circulation, which strongly influences global climate.

"Webster, a sea-ice specialist at the University of Alaska Fairbanks Geophysical Institute, will in a few days board flights that will carry her across the globe to Svalbard. From there, she will carry her bag upon a 35-passenger aircraft. She will then fly more than 500 miles northward before landing on an ice runway and riding a snowmachine to the research vessel Polarstern, an icebreaker that has been twirling in the sea ice of the Arctic Ocean since last October."

On the cusp of Interior Alaska’s springtime, Melinda Webster will not experience it this year. She’ll miss most of summer, too. Webster will soon head north of Earth’s land masses, to spend the next half year cradled in ice.

As earth and space scientists change teaching practices to accommodate social distancing during the pandemic COVID-19 / Coronavirus outbreak, we wanted to share tips and tricks for creating a better online educational experience for K-20+ students in the field, lab or classroom.

Spring field trips are canceled, which makes it really hard to get students charged up about Earth sciences. Here's a selection of virtual field trips that can't replace the real thing, but may help students not lose interest, and may even whet their appetites for the day we can venture out again, f...

A “new” video has emerged of the Tohoku tsunami racing inland in a Japanese port town. I don’t know that it’s never been released before, but I sure haven’t seen it, and I’ve seen basically all of them. The video is embedded at the end of this post. Update 8/19/13: I have changed the vid...

The relatively squat and gangly humpback whale moves more efficiently through the water than its sleeker, larger cousin, the blue whale, according to new research that used devices attached to the animals to collect information about these large creatures.
The new research, being presented at the Ocean Sciences Meeting 2020 in San Diego this week, found size, not shape, matters most to efficient forward motion by blue, humpback and minke whales, but all the whales are highly efficient swimmers.

So now we are at the point of dumping the Fukushima waste water into the Pacific Ocean.
Somehow I knew it would come to this. The collective temperament of Human Kind would lead us to make mistakes this big. That our greed and arrogance of intellect would bring us to this point.
The nations responsible for pursuing this technology have bowed out and left Japan alone to deal with this technological and economically overwhelming challenge.
“It’s OK” we will be told, “it will not raise the background radiation levels of the Pacific Ocean measurably.”
The whole idea of trying to isolate a nuclear pile from water inflow with ice just begs reconsideration from anyone thinking above an 8th grade science level. But that’s what was attempted.
I suggest we not give up yet because the result of washing our hands of this mess is the equivalent of washing this disaster into the Pacific Ocean.
Pump a polymerizing slurry around and under the containment and start over; or whatever it takes to isolate this mess from intruding ground water. But don’t give up and just dump this mess into the sea.
